I was confused when the results first came in because my eyes went right for the chart, and I couldn't understand how I could have different percentages. 
Therefore, I fall in the 12% category.
From other info on the site:
Which U.S. cities are the most segregated residentially?
In the United States, racial segregation in housing is more pronounced in the North than the South. Here, for instance, are the eight most segregated cities with a population of at least 100,000 non-Hispanic Black Americans (based on a 2005 Black-White dissimilarity analysis of U.S. Census data):
Most Segregated U.S. Cities
1. Chicago, Illinois
2. New York City, New York
3. Atlanta, Georgia
4. Washington, DC
5. Newark, New Jersey
6. Philadelphia, Pennsylvania
7. Cleveland, Ohio
8. Boston, Massachusetts
With the exception of Atlanta and Washington, all of these cities are located in the North.
Which racial group in the U.S. is the most segregated in housing?
Segregation is often presented as a characteristic of minority populations such as Black people in inner cities, Native people on reservations, or Asian people in urban areas (e.g., Chinatown). When it comes to intergroup contact, however, the most racially segregated Americans tend to be White. Just as Black Africans are more likely than other Africans to go through their day seeing only Black people (due to the predominance of Black people in Africa), White Americans are more likely than other Americans to see only White people.
An interesting site.
